Dear Yogesh,
Covalency is the total no. of orbitals that is s,p,d and f present in the 
valence shell called co valency.
For example Al=> 1s2 2s2 2p6 3s2 3p1
The valency shell is here 3 therfore it covalecny would be => 3 + 3 = 6 (3 for s and 3 for p)
Maximum covalency would be that highest no. of orbital filled for an elemnt
for any quantum number.
.
Cheers!!
